    flammable gas detector

    Molecular Leakage Detector for flammable gas based on ultimate MPS™ technology.

    This flammable gas detector is a unique solution using the latest MPS™ (Molecular Property Spectrometry) technology to indicate the presence of flammable gases providing both a continuous signal proportional to the gas concentration and the activation via relay for alarming once a prefixed (and settable) level is reached.
    It combines all the advantages of MPS™ technology as in terms of long lifetime, no field calibration, built-in environmental compensation, no poisoning, wide temperature operating range and durability with a dedicated electronic board for easy interfacing the common control units thanks to the multiple outputs: Modbus, 2x Relays and 2x Analogue Output (ALL IN ONE).
